I propose developing a miniature electronic device that measures temperature, chest (lung and heart) movements, and oxygen saturation. This device would be placed on the chest of the monitored person.

The monitor is to be equipped with motion sensors (3D accelerometer, 3D gyroscope and 3D magnetometer,

Elevators are a critical element of "last mile" transportation infrastructure in high population density environments whose carrying capacity is severely constrained by recent social distancing recommendations.

Solar trackers have been used for decades. Trackers aim solar panels to continuously face the sun to maximize the energy captured. Concentrated photovoltaics (CPV), like conventional photovoltaic systems, generate electricity from sunlight. Compared to conventional photovoltaic systems, CPV are more efficient.

This gearbox has a large gear ratio (500), despite its compact size. The first stage is made in the form of a planetary gearbox, and the second in the form of a wave transmission. The device has a fairly good kinematic error, a large output torque,

A spray of spherical wastewater droplets into an extremely cold gas causes an ice shell to form and grow thicker and thicker as it falls downward in the spray chamber.

- Reversible operation of solid oxide cells will significantly increase market penetration capability of the solid oxide fuel cells (SOFC) due to the production of hydrogen and electricity at different operating modes. It can potentially address the energy storage grand challenge by leveraging hydrogen as the energy carrier medium.

Maintaining the thermal comfort of human bodies in hot weather is one of the most basic needs for life and is generally achieved with external active devices, such as air conditioners and fans. The utilization of these electricity-powered devices usually costs a considerable amount of energy.

This muffler is basically a combination of absorptive and reflective type and has 3 layers.

The inner one content a converging and diverging type of venturi with holes on it and a flap (can be a rhodium/palladium) in between the C/D venturi which diverts the exhaust gases.

There have been many great helmet designs for NFL players specifically to minimize the force of impact exerted by or on the players to prevent the players developing concussions. But what happens when player has an impact more than the helmet can protect?

When I had a heart attack recently, it occurred to me that the devices on the market for heart monitoring were woefully simplistic and in some cases inaccurate. And the fact that I couldn't go to cardiac rehab due to Covid-19 made it all the worse.
